Khan Academy: Comparing Positive and Negative Numbers on the Number Line

Make your own number line ... using a compass. The first installment of a 21-part series has scholars investigate positive and negative integers on a number line by using a compass to construct points that are the same distance from zero...

Take some notes on integers! Learners can use the number line and thermometer provided along the bottom and side of the page to help visualize and understand positive and negative numbers.

A different way to look at integers is on this number line with variables in place of numbers. Learners are to look at different expressions and describe why they think the answer would be positive or negative, depending on the location...

Using a number line can provide students with a concrete representation of the value various numbers hold. Sal plots 6 different numbers on a number line. He includes whole, decimal, and negative numbers.

Sal tackles pre-algebra in this series of videos, starting with the concept of negative numbers. Using a number line, he takes the viewer through different practical examples of negative numbers, such as temperature and bank accounts....
